[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laying machine for laying a heavy object such as a boundary block on a sidewalk of a vehicle, and more particularly to a self-propelled heavy object laying machine for laying a heavy object while traveling.

[0002]

2. Description of the Related Art Conventionally, most of the work of laying a boundary block of a sidewalk (small transportation and laying of blocks) is performed by using an auxiliary machine, and most of the work is performed by manual work. Is customary.

[0003]

[Problems to be Solved by the Invention] However, in the above-mentioned manual work mode regarding the laying of the boundary block,
For example, since a large weight of 80 kg (100 kg at maximum) is required to handle a block, it is difficult to lay the block easily and accurately, resulting in severe labor. For this reason, work time is required, work efficiency is low, and a large number of workers are required.
There is a need for skill.

[0004] That is, the conventional manual work mode for laying the boundary blocks has a problem in terms of workability and safety. In view of the above-mentioned conventional problems, the present invention moves and transports a heavy object such as a boundary block of a sidewalk to a target position, and can easily and accurately lay it without requiring power, thereby saving labor. It is an object of the present invention to provide a self-propelled heavy load laying machine capable of improving safety.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a self-propelled bogie and a pneumatic three-dimensional weightless balancer mounted on a base portion of a body of the self-propelled bogie. A swivel portion supported so as to be freely swivelable about a substantially vertical axis, a vertical arm portion connected to the swivel portion to be free to tilt in the horizontal direction and extending vertically upward, and the vertical arm An air-type three-dimensional weightless balancer configured to include a lateral arm portion that is vertically swingably connected to the front end portion and extends in the horizontal direction, and the base and the air-type three-dimensional weightless balancer. An automatic gradient correction device interposed therebetween, having an inclined surface of a predetermined angle on the upper surface, a fixed base fixed to the base,
The upper surface has an inclined surface of a predetermined angle coinciding with the inclined surface of the fixed base, and is arranged so as to be freely rotatable on the fixed base.
A turntable to which a mount that freely supports the air type three-dimensional weightless balancer is fixedly mounted, and a rotating unit that rotates the turntable, and an automatic gradient correction device including:
A heavy-weight holder that is freely suspended and supported by a suspension unit at the tip of the lateral arm unit, and a leveling scraper device that is mounted on a vehicle body front part of the self-propelled bogie. Configured.

[0006] A connecting tool may be provided at the rear of the body of the self-propelled bogie to detachably connect a towed truck towed by the self-propelled bogie.

[0007]

In this configuration, the self-propelled trolley travels and moves in any direction. Heavy objects such as boundary blocks of the vehicle sidewalk are held by heavy object holders. The heavy object held by the heavy object holder is swung in all directions by turning the swivel of the pneumatic three-dimensional weightless balancer, and the tilting of the vertical arm in the horizontal direction and the vertical movement of the horizontal arm are performed. Due to the swing of the direction, it moves within a predetermined operation range. In this way, the heavy object held by the heavy object holder is suspended, moved, and laid at a predetermined position without load.
By the scraper device attached to the front part of the vehicle body of the self-propelled bogie, it is possible to level an irregular road surface, for example, a road surface which is formed in a transversely and longitudinally uneven shape.

If a heavy object exceeding the rated load is lifted by a load detector (not shown) that detects the load of a heavy object suspended from the hook 22 and the load detector detects the load, the heavy object is separated from the ground. A device is provided for automatically blocking

Next, the operation of the self-propelled block laying machine having such a configuration will be described. The self-propelled trolley 1 has an engine 12
, And is moved in an arbitrary direction by operating the handle 45. Car sidewalk boundary block 14
Is disposed between the holding plate portions 7a of the chuck 8 and is held between the holding plate portions 7a which are closed by the upward movement of the hooks 22 as described above.

The hook 22 is turned in all directions indicated by X in FIG. 2 by turning the turntable 15 of the pneumatic three-dimensional weightless balancer 5, and the vertical arm 1 is turned.
6 moves in a predetermined operation range by the horizontal tilt of 6 and the vertical swing of the horizontal arm 17. In this case, the operation range of the point A in FIG. 1 is a hatched portion Y in FIG. 1, and the position of the hook 22 indicated by the two-dot chain line in FIG. 1 is the lower limit position.

In this manner, the block 14 chucked by the chuck 8 is suspended and moved to a predetermined position with no load, and is laid. Further, the simple scraper device 8 attached to the front portion of the vehicle body 2 of the self-propelled bogie 1 makes it possible to level an irregular road surface, for example, a road surface formed in a transversely and longitudinally uneven shape.

According to the self-propelled block laying machine having such a configuration, the block 14 can be moved at any place by traveling.
Can be laid at any position. In particular, if the block 14 is within the allowable hanging load, the block 14 can be hung under no load, so that the movement and positioning of the block 14 can be easily performed only by touching an operator's hand.

Further, since the self-propelled block laying machine of this configuration includes the simple scraper device 8, the block 14
In addition to the laying of uneven ground surface, for example, it is also possible to perform a simple earth removal work or terrain on a road surface formed in an uneven shape in a cross-section, longitudinally, because the automatic slope correction device 4 is provided, By the leveling by the scraper device 8,
The laying operation can be easily performed on a vertically formed gradient road surface.

Therefore, the form of manual work related to the laying of the boundary block 14 can be eliminated, severe labor can be eliminated, work time can be reduced, work efficiency can be improved, and the number of workers can be reduced. In addition, danger can be eliminated and there is no need for skill. Further, according to the above embodiment, since the connecting tool 10 for detachably connecting the towed vehicle 9 towed by the self-propelled vehicle 1 to the rear of the vehicle body 2 is provided, the towed vehicle 9 may be provided with a block or other components. Work equipment etc. can be loaded and towed, which is convenient for block construction.
